Metallic Map Validator
Measure ambiguous metalness without erasing legitimate dirt and transitions.
Measure metallic-map grayscale consistency, black/white coverage, ambiguous midtones, alpha, seams, and linear-data expectations in-browser.
Drop a metallic or metalness map
Inspect supported images and ZIP entries locally in your browser. PLAYTEX AI compares the maps as a set, labels measured checks separately from visual heuristics, and shows the evidence behind each finding.
- Grayscale consistency
- Black, white, and midtone coverage
- Color-space metadata
- Unused alpha
- Tile-edge continuity
Pricing: This focused check and its evidence are free. Complete Material Preflight and engine-ready repair packaging require Starter or higher.
Should a metallic map be only black and white?
Most clean material regions are dielectric or metallic, so black and white should dominate. Intermediate values can still represent blended pixels, dirt, corrosion, or antialiasing. A useful validator reports the midtone percentage and spatial evidence; it should not blindly threshold the map.
How the check works
- Upload the source files. Choose the real material maps or a ZIP so dimensions, channels, filenames, and decoded pixel samples can be checked together.
- Review measured evidence. Open each finding to see the affected map, observed value, confidence, and proposed repair instead of a generic pass or fail.
- Export deliberately. Choose an engine target, keep or disable individual repairs, and download renamed maps plus an import-settings report.
Confidence matters: dimensions, alpha ranges, vector length, edge differences, and memory are measured directly. Map meaning, baked lighting, useful resolution, and normal orientation can need filenames, a target choice, or artist review.
Metallic Map Validator FAQ
Are uploaded textures sent to a server?
No. Supported images and ZIP entries are decoded, sampled, and repaired locally in the browser. Closing the page clears the working set unless you download an export.
Why does PLAYTEX AI not automatically threshold every metallic map?
Thresholding can destroy intentional grime, edge antialiasing, and layered-material transitions. Midtones are flagged with coverage statistics for artist review.
What does Roblox expect?
Roblox documents black as non-metal, white as metal, and notes that most values are near those endpoints while intermediate values can represent dirt or grunge.
